Balancing device for a bar loading magazine

A balancing device for a bar loading magazine for guiding material bars on a turning machine, wherein a z axis is defined by the longitudinal axis of a material bar guided in said bar loading magazine, comprising

• at least one guiding unit designed for receiving and introducing a material bar, along the z axis and which allows the material bar introduced and conveyed for being machined on the turning machine to be rotationally supported, and wherein said guiding unit is designed in such a way that such a rotation of the introduced material bar is carried out about a rotary axis that extends either coaxially with or offset from the z axis, and characterized by
• at least one mass body that can be repeatedly positioned in relation to said guiding unit, which mass body, each time it has been positioned, is in at least one of a positive connection and a-non-positive connection with at least one of said guiding unit and the material bar, so that said mass body rotates, during rotation of an introduced material bar, together with said material bar at the same angular speed about the rotary axis, and
• at least one positioning unit which is designed to bring for a first time the at least one mass body into a position in relation to said guiding unit, to detect during the rotation any repositioning that might be necessary because of an imbalance, and to reposition said mass body in each case in response to the detection of a required repositioning in relation to said guiding unit.
